I agree, whole 8.5.0 is crap. For example, i have ssh port not 22, but 100 and after update "Configure -> Servers -> mail.domain.tld" stop working. (zmserverips ..... with Error code: service.FAILURE Details:soap:Receiver)
Yes - i know:
zmprov mcf zimbraRemoteManagementPort 100
ssh -vi .ssh/zimbra_identity -o strictHostKeyChecking=no email@example.com
And it works OK, so problem is not in sshd. I have disabled SElinux, firewall is OK, rights are OK, i tried generating new ssh keys, zmfixperms, ... i read Mail
Queue Monitoring - Zimbra :: Wiki but nothing works.
In /var/log/secure is:
Aug 28 11:02:25 router sshd: Accepted publickey for zimbra from 192.168.1.254 port 56146 ssh2
Aug 28 11:02:26 router sshd: pam_unix(sshd:session): session opened for user zimbra by (uid=0)
Aug 28 11:02:28 router sshd: Received disconnect from 192.168.1.254: 11: Closed due to user request.
Aug 28 11:02:28 router sshd: pam_unix(sshd:session): session closed for user zimbra
So in sshd is really no problem.
I thought that update something broke, so i make clean install (./install -u, remove all from /opt, reboot, ./install) and still this error. In addition in clean install i cannot create new domain.
Problem is only in 8.5.0 when i downgrade from backup everything works.
I really love this project and Zimbra developers are for me heroes, but version 8.5.0 is not final version, it is not even beta, it is heavy alpha. This errors are shame.
Sorry for my bad english - i hope that you understand me
